Opis:
COVID-19 has created a dramatic and rapid transition to emergency remote teaching in higher education (HE) creating both new opportunities and challenges for lecturers and their students. As HE adapts to these new circumstances, there is a need for instructors to design and teach classes that support collaborative learning and increase opportunities for student interactivity. This article reports on an ongoing study exploring university students’ experiences and perceptions of using breakout rooms (BRs), a technical feature of many synchronous online platforms, as part of their online classes. Using a mixed methods research approach, 127 students, who were registered on English language courses at a university in Cyprus during Spring 2021, participated in the study. Findings indicate that students’ experiences and perceptions of breakout rooms during this period were impacted in five key areas: (1) emotional/affective, (2) moral/ethical, (3) social, (4) pedagogical and (5) technological. These findings suggest that students’ personal feelings, attitudes to online learning, sense of connectedness to their peers, expectations of the role and presence of the lecturer and issues relating to the technology, are all considered to be significant factors in their use of BRs. This study offers initial insights for educators who wish to use, modify and/or adapt synchronous online teaching to incorporate collaborative learning opportunities through breakout rooms.

Opis:
At the end of the year 2012, Food and Chemical Toxicology published a long-term study by Seralini et al., describing the safety evaluation of genetically modified NK603 maize and Roundup herbicide. Contrary to previous, short-term studies, this experiment revealed some negative effects of these substances on the health of experimental animals. GM feeds and Roundup generate revenue worth millions of dollars. This may be the reason why Seralini’s paper has became the subject of much heated criticism, mainly from parties linked to business and agro-biotechnology. After one year of debate, the editors of Food Chem Toxicol. decided to retract the paper, an unprecedented event given that the published article was peer-reviewed and there was no evidence of plagiarism or fraud. Here, we stress the results of Seralini’s study, discuss the methodological hints of that work and cite the commentaries on the whole situation.

Opis:
The Rakushechny Yar site is a floodplain multi-layer archaeological site encompassing strata dated from the Early Neolithic to the Bronze Age. It is characterised by a complex stratigraphy, with the presence of different deposits, buried soils and archaeological layers. Fluvial deposits interlay different settlement strata, which provides an opportunity to elaborate a precise chronological scheme and to study the successive changes in hydrological regime, climate and vegetation, along with the phases of human occupation. A study of the pastes used in ceramic manufacture was conducted to investigate changes in the procuring of raw materials, whose procurement would have depended heavily on their availability and sedimentation process. The fluvial deposits, which have safely preserved the Neolithic–Bronze Age archaeological layers, reach thicknesses of more than 6 m, which makes this site interesting both for the reconstruction of the human–environmental interaction and for the palaeoenvironmental history of the region.

Opis:
The article presents the results of a study on sediment deposition processes in the palaeolake shore zone, at the multilayered Serteya II archaeological site in Western Russia. In recent years, geomorphological, palaeopedological and palaeoecological research was undertaken in strict cooperation with archaeological fieldwork. The Serteya II site occupies a substantial area of a kame terrace and biogenic plain within a palaeolake basin. From an archaeological point of view, the site is represented by few Mesolithic artefacts, but mostly by remnants of hunter–gatherer–fisher communities attributed in the Russian scientific tradition to the Neolithic period and dated from 6300 BC to 2000 BC. Later, the area was used by people in the Bronze Age, Early Iron Age and Early Middle Ages. The integration of archaeological and multidisciplinary palaeoenvironmental research allowed the natural and human induced deposition of mineral-organic and minerogenic sediments to be reconstructed, as well as the development of structures in the lake shore zone. The changes from lacustrine to fluvial system were documented and the human impact is recorded mostly in the acceleration of slope processes.

cosmogenic radionuclides
Opis:
Cosmogenic radionuclides in meteoroids are produced in space in the process of activation. These nuclides have various lifetimes in range from a few days to several hundred thousand years and can therefore be helpful in solving several problems related to the study of meteoroids and their remains, both in space and on the Earth. The simplest application of cosmogenic radionuclide decay in meteorites is to determine the terrestrial age of meteorites, especially those whose fall has not been observed. In this article, we present an additional application of cosmogenic radionuclide measurements, namely for the verification of origin of rocks that show equivocal features and may potentially represent meteorites.
